Came here on a Saturday for breakfast and the wait was about 15 minutes so we went elsewhere. The hostess was very courteous about it and we returned on Sunday morning for breakfast...what a hidden gem in Scottsdale! The food was excellent and the staff was very knowledgeable in their recommendations for breakfast.
I personally had the French toast and it was some of the best I've had. Fresh bread and it was presented very well on the plate.
The ambiance of Merci is just like a small Parisian Caffè and the patio is excellent with the choice of music.
I strongly recommend visiting if you are in the area. I will be back for lunch and dinner for sure!
